Moon Township police set up a hidden camera along Montour Trail after four indecent exposures were reported there this month.
They've captured photos of a person of interest, and now, they're seeking help identifying him.
The camera was on a path to a rocky cliff along the trail and captured images of a man -- consistent with descriptions given by victims -- just before the last incident, in which a man, naked from the waist down, fondled his genitals in view of a female runner.
In the photos, the man had his hand in his pants and held a bag, police said in a press release. Police believe the white or bi-racial man puts a wig on before exposing himself.
The incidents occurred in the morning or early afternoon: 9:46 a.m. July 8; 1:07 p.m. July 13; 11:18 a.m. July 19; and 8:33 a.m. July 24.
